“…The nal stage of the thermal weight loss of the four groups of bottom sludge may result from the further combustion of residual coke products produced during the previous pyrolysis process [49] . After the pyrolysis process, the unpyrolyzed residue of the original bottom mud is the largest, displaying that the original sediment contains higher mineral elements, and also verifying to a certain extent that phytoremediation has a transport effect on the mineral elements in the sediment [50] .…”

Purpose HDS sediment is a type of solid waste produced when the high-concentration mud method (HDS) is adopted to treat acid wastewater from copper mines. It can rationally utilize sediment resources by using phytoremediation. Methods To reveal the effect of different phytoremediation on the heavy metal, enrichment capacity and microbial diversity of the HDS sediments of copper mines, in this experiment, the HDS sediments of a copper mine without phytoremediation were selected as the control group, while the sediments of black locust (Robinia pseudoacacia), slash pine (Pinus elliottii Engelmann) and Chinese white poplar (Populus tomentosa Carr.) were used as test groups to analyze the physical and chemical properties, heavy metal pollution and bioaccumulation capacity of HDS sediments under three phytoremediation. Results The results show that different phytoremediation can reduce the sediment's conductivity and adjust the sediment's pH value to the range suitable for plant growth. The BCFShoot and BTF values of Chinese white poplar to Cd and Zn and slash pine to Pb were both greater than 1. Conclusions As discovered from the bioconcentration coefficient and biotransport coefficient results, Chinese white poplar is an enriched plant of Cd and Zn, while slash pine is a plant full of Pb.

“…At the same CO 2 concentrations (550 ppm), the ability of F. arundinacea to reduce Cd in the intercrop decreased by 215.0%. Thus, this study well demonstrates that, in the phytoremediation design, it is essential also to assess the main interactions between possible environmental variables to achieve an effective, resilient and sustainable remediation system in the context of the ongoing evolution of contaminant behavior [73].…”

Pollution from numerous contaminants due to many anthropogenic activities affects soils quality. Industrialized countries have many contaminated sites; their remediation is a priority in environmental legislation. The aim of this overview is to consider the evolution of soil remediation from consolidated invasive technologies to environmentally friendly green strategies. The selection of technology is no longer exclusively based on eliminating the source of pollution but aims at remediation, which includes the recovery of soil quality. “Green remediation” appears to be the key to addressing the issue of remediation of contaminated sites as it focuses on environmental quality, including the preservation of the environment. Further developments in green remediation reflect the aim of promoting clean-up strategies that also address the effects of climate change. Sustainable and resilient remediation faces the environmental challenge of achieving targets while reducing the environmental damage caused by clean-up interventions and must involve an awareness that social systems and environmental systems are closely connected.

“…It is worth noting that these two metals are generally transported gradually from the roots to aerial parts (twigs, leaves) via transpiration flow. The efficiency of uptake and/or translocation of these elements may be dependent on many other elements (Mac-Farlane et al 2007;Takenaka et al 2009) or the general influence of environmental factors such as pH, cation exchange capacity (CEC), clay component or redox potential (Magdziak et al 2015). Trees, like many other plants, are able to mobilise different defence mechanisms during their exposure to the presence of toxic elements.…”

The phytoextraction of toxic elements present in industrial wastes by selected tree species seems to offer an interesting alternative to hyperaccumulators, which are generally highly effective but small. For this reason, the study aimed to compare the potential of 1-and 2-year-old Tilia cordata Miller and Ulmus laevis Pall seedlings growing on a mixture of wastes (flotation tailings and sewage sludges) in the environment. One-year-old T. cordata was the only plant unable to grow successfully. A general decrease in tree biomass was observed following their growth on the waste mixture. The mean biomass of 2-year-old T. cordata and U. laevis seedlings was 59.5 ± 1.6 and 57.0 ± 8.6 g, respectively, whereas that of 1-year-old T. cordata was 16.0 ± 9.3 g. These values were 46.2, 48.0 and 50.5% lower than those determined for the control trees. Phytoextraction of 67 elements in particular organs of trees in many cases was significantly diverse. According to the Friedman rank sum test, T. cordata (1y) and U. laevis (2y) growing in soil were the only plants that differed as regards their ability to phytoextract elements. In the case of trees growing on the waste mixture, the most effective accumulating plants were seedlings of 2-yearold T. cordata. Significantly lower efficiency was observed for 2-year-old U. laevis, while the lowest efficiency was recorded for 1-year-old T. cordata. The obtained results unambiguously pointed to the significant role of a proper selection of tree species concerning their age for phytoextraction of elements from polluted substrates.
